Review on Dorman 603 257 Coolant Reservoir by Dhoal Black

Revainrating 3 out of 5

Coolant reservoir smaller than stock

The tank is numbered and looks the same but is smaller than the original standard Mercedes Benz cls550 reservoir. I installed it tonight and will update my stars depending on how things go. 3 stars only because of the size. I'm not sure how size affects anything, but I think Mercedes used a tank this size for a reason.

Pros
  • Robust construction using quality materials to withstand heat and vibration under the hood
Cons
  • Interchangeable
